Bail out the window and run like a wild man! You should always dial 911... If you can't for whatever reason and you have a wife and kids like me, then a knife may be your only hope. I'll die fighting with a knife before I let my family get hurt. Without the knife I'd have to use my fists. That said, I don't plan on dying! Hopefully it doesn't ever happen.
"If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun." The Dalai Llama (5/15/01, The Seattle Times)
"That rifle on the wall of the labourer's cottage or working class flat is the symbol of democracy. It is our job to see that it stays there." George Orwell
